Rambla de las Sarguillas is the chief left-bank tributary of the Hoz Seca in the municipality of Checa. It represents a Mediterranean limestone mountain stream preserved in such natural state that it holds River Nature Reserve status.
Water has sculpted an entrenched gorge through limestone and dolomite over gravel beds. Flow is highly intermittent: much of the surface runoff rapidly infiltrates the porous karst substrate to circulate underground.
For this reason, the Sarguilla and Hoz Seca are best understood together: what looks like a dry stony wash is an active conduit of the subterranean hydrological network.
